Houston crime lab implicated in another possible wrongful conviction


Twenty two years after being wrongfully convicted for a rape and robbery in Texas, a Houston man may be released on bail this week on the heels of new DNA tests proving his innocence.

Gary Alvin Richard was arrested for the January 1987 attack of a 22-year-old nursing student and was convicted based largely on evidence processed by the Houston Police Department crime lab, the same lab that came under fire in 2002 after local reports raised questions about the quality of DNA testing. According to the Houston Chronicle, there are a number of problems with Richard’s case:

The victim identified him some seven months after the attack. HPD crime lab analysts came to conflicting conclusions about the evidence, but reported only the results favorable to the case. Physical evidence collected in what is known as a “rape kit” has been destroyed, a victim of poor evidence preservation practices, leaving nothing for DNA testing now.

During his original trial, HPD crime lab supervisor James Bolding testified that Richard was a non-secretor, meaning that analysts would not be able to determine Richard’s blood type through his body fluids. However, while tests done last week confirmed that semen from the rape kit came from a non-secretor, it also showed that Richard is a secretor. Therefore, the semen found on the rape kit could not be his.

While Richard’s defense claims that the blood tests prove his innocence, prosecutors aren’t as sure. The Houston District Attorney’s office concedes that Richard should be released on bail, but has said that it is too early in the reexamination process to clear Richard of all charges. Three Harris County men have already been proven innocent through DNA testing after mistakes at the HPD crime lab led to their wrongful convictions:
